DEEP-WELL-PUMP LUBRICAT'IN'.

To allwlwm t may concern:

Be it known that I, VICTOR SCHLEYER, a citizen of the United States, residing at Anderson, in the county of Madison and State have invented a new and useful Deep-Well-Pump Lubrication, of which the following is a specification. v

It is the object of my `invention to provide an ecient lubricatinglsystem for deep-well The accompanying drawing illustrates my invention: The single figure of such drawing isy a vertical central section through a deep-well pump embodying7 my invention,

' the upper part of the structure.

The pump shown is a multi-stagepump, havin a plurality. of runners 10 mounted on a slaft 11 which extends down into the from the top 'of the Wellwhere it is rovided with any suitable driving means. he pump has the usual casing 12 around the runners 10, and the usual bearings 13, of any desired type, one above each ofthe run-v '25 ners 10. The upper bearing 13 has an annular flange 14 at its upper end, on whlch 1s box 16 around ate 15 rests the The a plate 15 which has a stufiin footing of a bearing 17 for the shaft 11. and above it, and the flange 14, the edge of the plate 15, and the footing of the bearlng 17 are bolted together by suitable clamping bolts. From the top of the bearing 17 a Y pipe 20 surrounding the shaft 11 extends upward to the top of the well, to provide a lubricant-passage around the shaft from a supply tank 21, which is connected by a pipe 22 to the pipel 2O near its upper end.

The pipe 20 and shaft 11 extend centrally of the water-discharge pipe 23 leading up from the pump. I f

Below the lowerrunner 10 the shaft 1 1 is 4provided with a tail bearing 24, suitably supported by-a spider 25 from the inlely @casing 26 of the pump. At the upper end of the tail bearing 24 is a joint 27 as nearly water tight as possible with the shaft 11,

and near such upper end is an annular chamber 28 .which is connected by a pipe 29 to the space 19 between the plate 15 and the bearing the shaft 11 is the runnerl 30 of a small lubricant pump, mounted in a casing 31 sup- 56 ported from the bearing`24. The intake of Specification of Letters Patent.

the runner 30 opens to a chamber 32 at lthe lower end of the bearing 24. The runner discharges outwardly by centrifugal force apipe 34 to a plurality of ducts 35 leading respectively to the several pump bearings 13.. The discharge chamber 33 is also connected by a pipe 37 to the tank 21, preferably dischar ing into such tank above a screen 38 therein, while the pipe 22 leads from the tank 21 below such screen, sokthat the screen filters the lubricant which flows out from the tank. The entrance from the discharge chamber 33 of the lubricant pump to the pipe 34 is preferably smaller than that to the pipe 37, so that the greater part of the lubrlcant discharged from the lubricatin pump will be returned to thetank 21; an in the entrance to the pipe 34 from the chamber 33 I preferably provide a check valve 39 which prevents the possibility of back flow of.any liquid fromy the pipe 34 into such kdischarge chamber 33. Preferably I provide a hand valve 40 in the 'pipe 37,

upper end. thereof, by the manipulation of which hand valve the relative amounts of lubricant discharged through the n operation, the lubricant from the tank 2,1, which is kept filled, is supplied bythe pipe 22 to the shaft-surrounding pipe 20, whence it is fed downward, past any bearingl 36`which may be provided within said pipe 20- for the shaft, to and through the bearing 17 and into the space 19, Thence it passes by the pipe 29 to the chamber 28, and '24 to the space 32. 32 it is drawn by the sucking action of the runner 30 and thrown into the discharge chamber 33, and fed therefrom by way of the pipe 37 back tothe tank 21 and by way of the pipe 34 and ducts 35 to and through the pump bearings 13. Thus the-pump bearings 13 are positively lubricated, by forced pressure, which pressure is sufficiently great to prevent water and sand from entering such bearings. The flow of lubricant through the pump bearings may be relatively small, if that is desired, to avoid 'contamination of the water pumped upward by the pumpin case the lubricant used is oil; and water 4is prevented from enterin the lubricant pump by the action of the c eck valve 39.
